Keep the process of a program running after closing the shell terminal

to keep the process running after the shell terminal close on ubuntu 16.04 use the following
command:

nohup my_command > my.log 2>&1 &

if you don't want to log the output of this command to a log file the replace my.log by
/dev/null, So it will be like the following:

nohup my_command > /dev/null 2>&1 &

if you want to find the process after a while and want to kill the process then, list all
the running processes:

ps -ef

you will find the command in the CMD column of the diplayed list. Now find the process Id from
the PID column and insert the kill command

sudo kill pid
